Be it known that I, J. W.- SUMMERS, of the town of Sandy Hill, State of New York, havein'vented certain new and useful Improvements in Steam Generator-stand I declare the following is a full, true, and exact description of the same, reference being had to the accompanying drawings, which form a part of these specifi cations, and the letters of reference marked thereon. r

Figure l'repre sents a front view of my generator and accompanying apparatus.

Letter A represents the pump-barrel, which is connected at bottom with the main distributing pipe 0. The pump-barrel Ais furnished with plunger B for acting upon. the'water within the pump A. D designates the air-chamber, which is connected with the delivery valve E, and is provided atQtop with a movable cap, F. Letter G represents a second distributing pipe, which is joined to the main distributing pipe (.3, from which it" passes up into the generator H. At the upperendof the distributing. pipe G is placed'thei'alve I, which is acted upon by the spring J. The letter K represents a foot-valve, immediately overiwhich is placed the waters valve L, the valve L being held down by thei' lever M, and weight N." At the point 0 is another waste-valve,. constructed and operated in' the same manner with the globular valve L, and in connection with the foot-valve K. H represents a vertical section of the generator, which is of .couicaljorm, the apex pointing downwards. Q represents thc tube for carrying the steam into the cylinder. At the point K the furnace is made to' inclinc inwards'at a slight angle, so as to reflect or radiate the heat directly'en the surface of the ge'nerator H. It will be remarked that the pressure can be obtained in the air-chamber D to any dcsireddegrlee by means of the two valves L and O, and the levers and weights attached to them, and that when the steam in the generator H exceeds the pressure in the air chambcrl), no water will entcr the generator, but will be forced out through thewates-valves L and 0, so that no more steam can be generated until the pressure in the generator falls.

below that in the air-chamber. D. It will be further observed that the generator H is'so formed that it presents its strongest part to the direct action of the fire, and will be, consequently, less injured by the heat. In order that the water injected into the generator H maybe instantaneous]; converted into steam it"will be. seen that the valve I is pressed upwards by spring J, and has to force its way by minute streams or spray into In operating my machine, the necessary quantity of water being introduced into the generator H byth e pump A, and steam raised to set the-pump in operation, the water will then be forced through the distributing valves into the generator H, and the pressure oi the steam will-increase until it is equal -to the weights which hold down the waste-valves, while the water not needed to keep the steam at agiven pressure will pass out from the waste-valves. I i l Having thus described my invention, what I claim, and desire to secure by LettcrsPatent, isi 1. The generator H, when constructed as and for the purpose herein described.

2. The air-chamber D, for the purpose of governing and controlling the pressure of steam inthe generator,

as and for the purpose set forth.

3. The valve I, for the purpose of dispersingthe water, in the manner and for the pnrposespecified.

4. The combination of the valves L, K, and O,- the"air-chamber'D,-and generator H, the wholecoustructed,

arranged, and operating as and forthcpnr-posc herein set forth."

In testimony that acknowledge the foregoiugns my own act, I hereby an; my signaturc in the presence' of two witnesses.
